EDGAR PECKHAM, OE KINGSTON, NEIV YORK, ASSIGNOR, BY MESNE ASSIGNMENTS,TO THE PECKHAM MOTOR TRUCK AND WHEEL COMPANY, OF SAME PLACE.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 467,896, dated January26, 1892.

Application filed October 30, 1890- Serial No. 369,789. (No model.)

To tZZZ whom it may concern:

Be it known that I, EDGAR PECKHAM, of Kingston, in the county of Ulster,in the State of New York, have invented new and useful Improvemen ts inCar-Brakes, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists, chiefly, in a novel, simple, and effectivesystem of levers for applying the brake to the track, as hereinafterfully described, and specifically set forth in the claims.

In the annexed drawings, Figure l is a side elevation of a car-truckequipped with my improved brake. Fig. 2 is a top plan View of the same,and Fig. 3 is an enlarged vertical longitudinal section on line y y,Fig. 2.

Similar letters of reference indicate corresponding parts.

A and A represent the usual longitudinal side and truss bars of thetruck-frame, which bars are generally attached to yokes b b, hung on thejournal-boxes c c of the car-axles C C.

a a represent the brake-shoes, which are arranged to bear on thetrack-rails, as shown in Figs. 1 and 2 of the drawings. For operatingsaid brake-shoes I employ on each side of the truck a two-armed lever orrock-arms (Z (Z, attached rigidly to a rock-shaft e, which is extendedacross the truck and is mounted in suitable bearings e, secured to thetrussbars A A. The rock-arms d d extend downward, and to the free end ofeach is connected one of the brake-shoes a The brake-shoes are heldnormally out of frictional contact with the track by means of suitablesprings g g, connecting the rock-arms to the truckframe. To the shaft(21 also rigidly secure crank-arms h h, the free ends of which areconnected by rods Z Z to the levers Z Z, which are pivoted vertically tothe truck-frame at the front and rear of the rock-shaft c and have theirupper ends connected to the rods 2, which are extended to theends of thecar and connected thereat to the brake-levers or brake-wheel shafts inthe usual and wellknown manner not necessary to be shown.

My described car-brake possesses several advantages, among which may benamed the employment of two brakeshoes on each side of the truck andoperated by one and the same rock-shaft and in such a manner that onlyone of said brake-shoes can at a time be applied to the track, and italways applies the shoe which is nearest the rear end of the car anddrags said shoe on the track, thereby avoiding the danger of the shoebecoming upset by catching on obstructions on the track; also, greaterpower for applying the brake is obtained by the employment of the leversZ, which are connected near their fulcrums to the cranks of therock-shaft.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The combination, with a car-truck, of the rock-shaft 6, provided withthe cranks h 71, the levers Z Z, pivoted to the truck, rods Z Z,connecting said levers to the cranks, rocka-rms attached to the shaft(2, and separate brake-shoes attached to the respective rockarms, as setforth.

2. The combination, with the car-truck, of the rock-shaft e, rock-arms d(1, extending in opposite directions and downward from said rock-shaft,separate drag-shoes a a, attached to the free ends of the rock-arms,cranks attached to the rock-shaft, and brake-levers connected to saidcranks, as set forth.

In testimony whereof I have hereunto signed my name this 10th day ofOctober, 1890.
